Well if everything else going on wasn't enough I just opened my game, found i'm back down to 74, all my event progress is gone (i did get a screenshot) and lost everything gifted and done in the last, looks like several days.
No reason.
No reason.

, it was set back 4 days after getting into the event the first time, and I didn't open ticket at that time and just played the event again. Now it went back to before the event again and the event is closed. I think I need to send a ticket in now. I think there were several others had this problem too.
